Wrong forum but...How did you figure out #4 is dead? Is it ohming out of range (12-14 ohms resistance), plugged, mechanic advice or??? If it's ohming in range or close to it try a bottle of Redline S1 Fuel System Cleaner in a 1/2 tank of gas and drive on the freeway nonstop for an hour. Q45 injectors are very similar to the 300zx injectors and the Redline additive can do wonders under the right circumstances. I get mine at Pep Boys or Napa for about $8/bottle.
